Current methods for screening violent offenders for program eligibility are expensive and time consuming. Developers of the Violent Offender Treatment Program (VOTP) have designed a brief and economical instrument to screen offenders for program eligibility. The present study was undertaken to assess the reliability and predictive accuracy of the VOTP Risk Assessment Scale (RAS). An interrater reliability of 20 court histories attained a mean kappa of .81. The RAS was applied to court histories of 202 violent offenders released between 1985 and 1987. A 10-year follow-up of convictions for violent behavior yielded a 47% base rate. Receiver Operating Characteristic curves showed that for varying time-at-risk periods, the predictive accuracy remained between .72 and .76. The recommended cutoff score for all time-at-risk periods was 11. The relatively high accuracy rate of the VOTP RAS indicated that it was accurate enough to aid program eligibility decisions.

<p>Informed by theories on offending behaviour, violent offender rehabilitation programmes aim to provide treatment to a group of individuals who have committed a diverse range of offences, from assault to aggravated robbery to murder. Yet despite progress with specific offence types (e.g., homicide, robbery, assault), there is no research describing the offence chain characteristics of such a heterogeneous sample of violent offences. This exploratory study uses the structured approach of the Pathways Model of Assault (PMA; Chambers, 2006) to code and catalogue similarities and differences in the offence characteristics of an archival heterogeneous sample of violent offences. Cluster analysis was also utilised to investigate whether it was possible to construct a parsimonious series of pathways to represent the offence process for this diverse sample. The resultant model, the Pathways Model of Violent Offences (PMVO) was constructed and 12 pathways were revealed. The results suggest that upon initial investigation, there appear to be common, shared characteristics among a heterogeneous sample of violent offences.</p>

This study compared the predictive validity of multiple indices of violence risk among 188 general population criminal offenders: Historical-Clinical-Risk Management-20 (HCR-20) Violence Risk Assessment Scheme, Violence Risk Appraisal Guide (VRAG), Violent Offender Risk Assessment Scale (VORAS), Hare Psychopathy Checklist-Revised (PCL-R), and Screening Version (PCL:SV). Several indices were related to violent recidivism with large statistical effect sizes: HCR-20 (Total, Clinical and Risk Management scales, structured risk judgments), VRAG, and behavioral scales of psychopathy measures. Multivariate analyses showed that HCR-20 indices were consistently related to violence and that the VRAG entered some analyses. Findings are inconsistent with a position of strict actuarial superiority, as HCR-20 structured risk judgments—an index of structured professional or clinical judgment—were as strongly related to violence.

Purpose The purpose of this paper is to examine temperament differences, notably effortful control and negative emotionality, and correlates that distinguish between homicide, violent sexual and other violent juvenile offenders. Exploring heterogeneity among violent offenders is relevant to intervention strategies and policy implications. Design/methodology/approach Demographic measures, temperament constructs and individual risk factor indicators were assessed across 30,303 violent juvenile offenders (including 397 homicide offenders) in Florida to assess their ability to distinguish among violent juvenile offender subgroups. Findings Analyses demonstrated temperament constructs distinguish among classifications of violent juvenile offenders with effortful control differentiating homicide and violent sexual offenders from other violent offenders, and negative emotionality distinguishing violent sexual from other violent offenders, with youth having greater negative emotionality and less effortful control being non-sexual violent offenders. Homicide offenders were more likely to be older, male and had histories of gang membership and weapon/firearm offending than other violent offenders, and evidenced greater negative emotionality than violent sexual offenders. Originality/value The differences across violent youthful offender subtypes suggest heterogeneity among violent offenders with distinct correlates more predictive of some subtypes than others. Additionally, the temperament constructs of effortful control and negative emotionality are useful in distinguishing violent offender subtypes, which points toward differing intervention/treatment strategies.
